To all @if/wm 'it may Concern.'

Be it known that ive, J Aeon RUPPERT, Jr., and Enxics'r SinonL, citizens of the United States, residing` at New vYork7 in the county olf New York and State ot' New York, have invented certain neiv and useful linproveinents in i-iutoniohile-Tires, of'wliich the followingis a specification.

This invention relates to tires for auto' inohile trucks and the like and its novelty consists in the construction and adaptation ol the paris, as will he more fully hereinafter )elated out.

The object ot the invention is to produce a strong tire, with a sloiv wearing tread,

suliicient elasticity for Aits purpose, easy toq inake and capable ot' readily being' put into placeaiid removed. and with few parts ivliicli parts are little likely to Ljet out ot' order, `which inay be quickly adjusted, repaired or reneived.

1n the drawings, there is illustrated a tire embodying the invention. v

Figure l is a side vieiv in miniature of a wheel provided with the tire; Fig. .2 is an edge view thereof; Fig. 3 is an enlarged section/of a portion of the tire taken 'on a plano al right angles to the axle; Fig. el

is a transverse ,section on the plane ot theline st-el in Fig-3; Fig. 5 is an enlarged section on the plane of the line in lfin. 1; Fin, (l is a perspective of one of the k g i. Tief. 7 is a perspective ot' one oit the treads: Fig. S is a perspective ot one ot the cushions; Fin: 9 is a perspective of one of the keys in a dil'lerent position from that shown in Fig. tl; and Fig. l0 is a perspective'ot` a portion of the r'iin.

ln the drawings, 10 is the huh of a wheel, 11, 11 are the spokes and 12 is Athe Jtelly. Outside of and encircling the lelly is a telly hand 135 preferably of steel and outside ot' that is a riin 14. having a circumferential flange 15 on each side and in the iniddle with a ser of transverse rilis 1G, each provide l \vith a key Way consisting` ot' a dovetailed upper section 17 slightly tapering Atoward its inner end.

(ushions 2O with outwardly extending' flanges 2l along their inner sides and made of ruhher or other suitable elastic material are adapted to he placed within the several recesses of the rim 14, formed by the ianges 15, 15, 15 and the ribs 16, 16.

Treads 3() are inade of steel or other suitable material of a general shape conforming to the .shape ot the cushions 2() and are intended snugly to fit over such cushions.

The treads are each provided' lwith outwardly extending 'flanges 31, -31

and each side L1 is provided With a tooth L110 adapted to tit into the corresponding recess 310- of the tread with which it engages. ribs 1G between the outer flange and middle flange on one side are staggered with respect to the rihs het-Ween the middle flange and outer flange on the other side, so that When the parts are assembled. the treads on each one ot these tires Will he staggered with respect to those on the other.

lllhen the parts are te he assembled a cushion 2i) -is yput into one of the recesses of the riin lll, and a siinilar cushion is placed in the adjoining recess. @ver cach of these cushions is placed one ot the treads 30. The thickness et the flanges 2l' and 31 are so arranged that the treads inust be pressed slightl y and the flanges of the cushion com- ,pressed in order that the llanige 31 shall clear The riin 14 is so arranged that the I mi 1.17m n L Wheel, or the ikc, hav led with 'Ll'uusvcre ribs; 1h n key Way 0:1 @mkh 5MG, 50 wh lnier; fi Hangs@ beybss 'mvl with similar Hanger; hcmlion, a key adapted to QA-0 rb 0n will Sides und many each' lim.
